To all whom 'it may concern.:

Be it known that I, Li'ioN Wyss, a' citizen of the Swiss Republic, residing at La Chauxdc-Fonds, Switzerland, have invented new and uselul Improvements in Clocks and Watches, oi" which the following is a specification.

My invention relates to clocks or watches, particularly those designed to be ailixed to an automobile or other vehicle, and has lor its object the provision of inea-ns bywhich the winding of the spring and the setting of .the hands maybe accomplished by'rotating the bezel. 1

My invention consists in the construction, combination, and arrangement of parts herein described and claimed, and illustrated in the accompanying drawings 'forming part of this specification, which illustrate a preferred embodiment of my invention.

Figure 1 is a partial section through the casing taken approximately along the axis of the stem ot a time piece embodying the invention; and

F ig. 2 is a top View otpart of the timepiece.

I' Similar charactersof reference indicate corresponding parts in all. igu res ci' the drawings. l

In the embodiment shown, a casing 1 is provided l'iaving a base plate 2 by'n'ieans of which it may be attachedv to the instrument board of' an automobile or the. like, the tas-v ing 1 being adapted to contain, the usual clock or watch mechanism.

Rotatahly mounted on the casing 1 is thebezel 3 carrying the usual lens or glass 4: which is located in front of the face of the timepiece. The bezel may-be held in place by a screw or pin (not shown) adapted to engage the groove 5 which encircles the cas-4 the mechanism actuated by the stem 6 being that in common use, and not shown in the drawing.

The stem G'has associated withit `for rotation therewith a gear wheel or pinion 7,

-in the wall oi' ing engagement with said stem to rotate the Specieationof Letters-Patent. patented Dian 192% Appncanon'aica nay 4, issn.4 serial no. 466,634.

which is preferably provided with a longitudinally extending sleeve portion 8 journaled in the casing 1, and held in place by the lianged portion 9. The stem 6 is lono'itudinally slidable through the gear 7, lit may be squared to lit a corresponding hole in the gear, or otherwise arranged so that rotation of the gear causes the stein to turn.

The bezel 3 is provided with a toothed annular member 10 arranged in mesh with the gear wheel or pinion 7, so that rotation of the bezel, which may be effected by hand, causes rotation of the wheel 7 and stem (i, to wind the spring if the stein G is iii normal position.

The outer end of the stein 6 pi'eiterablv projects beyond the casing and is provided with an annular groove 11 adapted to be engaged by a lever 12 pivoted at 13 to the caslng, so that draw on the lever 12 causes 'longitudinal movement of the stem G from thenormal or winding position to the setting position.

The operation of the device is therefore as follows: To wind the mechanism, turn .the bezel 3, which through the toothed meniber 1() rotates the pinion 7 and hence the stein 6 which operates in the usual manner to wind the spring. To set the hands, draw the lever 12, moving the stem 6 so as to release the winding mechanism -and engage the setting mechanism lin the usual manner and then turn the bezel 3, thus rotating the stem 6 and thereby the usual setting mechanism. It will be noted that because of the mount ing of the pinion 'in the casing, the stein 6 is subject only to torsional stress, and any lateral pressure that is transmitted to the pinion 7 from the toothed member l() is taken up through the sleeve 8 by the casing. Having now described my invention, I claim and desire to secure by Letters Patent: l. In a watch or clock, the combination comprising a. casing, a stem for winding and setting, a pinion mounted for rotation tlc casing and having a slidstem, a bezel, and teeth on said bezel arranged to engage and aetuate the said pinion. 2. ln a watch or clock, the combination coinprising'a casing, a stem for winding and setting, a pinion mounted for rotation in the wall of the casing and having a sliding engagement with said stein to rotate the stein, a bezel, teeth on said bezel arranged to cngi-ge and act-nate the said pinion, and means tor sliding said stein between winding and settimo positions.

3. ii a wziteh or clock, the combination comprising a casing, n stem for winding und setting, u pinion mounted for rot-ation in the wall of the casing und having a sliding envugement with said stem to rotate the stem,

ii bezel, teeth on said bezel arranged to engage und netuate the said pinion, und a lever Iulgnumed on t11e .cusi,ugzu1d engaging Suid stem to effect movement thereof between windingund setting positions.

In testimony whereof 1 have signed my nume to this specification.

LON WYSS.
